Y doesn't vary directly with x
Answer: (2, -25)
Step-by-step explanation:
The x coordinate of the vertex is
.
When x=2,
.
So, the vertex is (2, -25).
Answer: a) 0.9961, b) 0.9886
Step-by-step explanation:
Since we have given that
Probability that does not show up = 0.10
Probability that show up = 0.90
Here, we use "Binomial distribution":
n = 125 and p = 0.90
Number of passengers that hold in a flight = 120
a) What is the probability that every passenger who shows up can take the flight?

(b) What is the probability that the flight departs with empty seats?

Hence, a) 0.9961, b) 0.9886
